WILLIAM ZIMMERMAN, OF BLOOMINGTON, ILLINOIS.

Letters Patent No. 88,255, dated March 23, 1869.

IMPROVED TABLE-ATTACHMENT I'OR CHAIRS.

' The Schedule referred to in these Letters Patent and making part ofthe name.

To all whom it may concern.-

Be it known that I, \VILLIAM ZIMMERMAN, of Bloomhave made a new anduseful I mprovcmcnt in Table-Attachment for Chairs; and I do herebydeclare the following to be a full, clear, and exact description of thesame, suificientto enable those skilled in the artto which it pertains,to manufacture and use it, reference being had to the accompanyingdrawings, forming part of this specification, and in which-- Figure 1represents my improved attzwhment, in perspective, adjusted to a chair;v

Figure 2, a side elevation; and

Figure 3, an upper-and under view of the table A,

showing its construction more fully, and exhibiting the difi'erent partsof the same.

Figures 4, 5, 6, 7, and 8, show separate parts of the I attachment, withtheir construction.

Like letters refer to similar parts of my improvement.

My invention consists in a device formed of several parts, to be used asan attachment for chairs, which can he used as a'table, book-stand, orrest, 850., and is particularly described as follows:

A represents the table, which is supplied with the pockets, orportfolios I and F, the former on top, the latter underneath, as shownin figs..l and 2.

E is a metal plate, containing a. socket and bar a, to receive and graspthe hook 12, upon the upper end of the hollow metal stand B.

It is not necessary that this standard be made hollow, but it ispreferably constructed thus, for the reason that it is lighter, and maybe easily adjusted, by meansof the screw and clamp, and theextension-rod V G, or a straight rod in place thereof, exactly to theheight desired by the occupant of the chair.

' At the bottom of B is a hook, m, to take hold of the round of thechair, and, in case there is no round, then a claw may be used instead,or a clamp, to fasten it to the leg of the chair.

K represents a clamp, which is designed to fasten the standard 13 to thechair.

I is a pad, or piece of wood or metal, fastened to the hollow part h t,by means of a rivet, or in' any other suitable manner, as shown in fig.(3, which is a top view of the clamp K, seen in ligs. 1 and 4.

The inner cylinder 71, fig. 5, by its shape, taken in connection withthe shape of the outer shell -i-,'to which it is fastened by a rivet, orpivot 1), enables one. by means of it and the thumb-screw I, to clampthe rod 13,

whichs upports the table A, firmly to the chair, as will hereafter morefully appear.

B", fig. 7, represents a standard of wood, with metal tips b an, thelatter supplied with a thumb-screw, to enable the occupant of'a chair toadjust the height of the reading-table for use.

G, fig. 7, shows a sectional view of the clamps to he used, which workwith a screw-thread upon the standard, although they may, if desired, bearranged as in figs. and 4.

Fig. 8 shows another modified form in which the standard B may beconstructed, the same being in two parts, the lower hollow, and theupper part sliding in it, as the parts of the telescope, being retainedat any desired height by a sct-scrcw, l. ington, in the county ofMcLean, and State of Illinois,

O, figs. 1 and 3, is a forked brace, hinged to one end or edge of thetable A, and cxtendin g downward, toward the centre, grasping thestandard B by the sliding collar D, jointed to the brace O at 0:, andsupplied with a thumb-screw, to fasten it at any desired height, thusgiving the table A any wished-for inclination. This collar may beconstructed, as in fig. 3, with a. hasp, as

seen at D.

E, fig. 2, represents a top view and side elevation of the metal platefastened underneath the table A, as seen in fig. 3.

G, fig 3, is a device which may be attached to the under side of thetable, by means of the cleats g, which are furnished with a mortise onthe side next to the table, to receive its arm G, and consists of metalor wood, with a net, R, at the outer end, and an opening large enough toreceive a bottle of ink. The same device is seen, also, at G, fig. 1.

H is a lamp-stand attached to the rod 0, which slides into thehollow-bcnt standard 11, which itself is fitted with the collar g, toslip over the standard B.

y and ll are supplied with thumb-screws, e and f, to regulate theheight.

V G, fig. 1, represents a device, composed of a bent rod, slipping intothe standard B, as hcrcinbefore de scribed. The object of this is tocarry the table A further from the body, when it is desirable to use itas a work-stand, 850.

In order to fasten my attachment to a chair, place the standard B sothat the hook m will grasp one of the lower rounds. Draw it up snug,thenlet down the clamp K, until the part, or pad J, rests upon the chairseat; The spur 0 is .then made to enter one of the notches, n, and thethumb-screw l is then turned in which passes directly upon the spur 0,and prevents it from comingout, and the outside shell, or claw i,turning upon its centrg p, the piece K is forced down upon thechair-scat, thus securing the stand firmly to the chair, in an uprightposition.

The table A may be made of any desired size, and also the standard B andaccompanying parts.

The table can be made with hinges, so it may be doubled up, forconvenience in carrying, and the standards may also he in joints shortenough to he put into an ordinary valisc when travelling.

Having thus described my improvement,

What I claim as new, and of my own invention, is-

1. The construction and arrangement of the standard B, the clamp K, thetable A, the metal plate E, the hinged forked brace 0, combined tooperate substantially as set forth.

2. The adjustable hinged clamp K, consisting of the parts J h i o pconstructed and arranged substantially as and for the purpose described.

To the above specification of my invention, I have signed my hand, this2d day of February, 1869.

WM. ZIMMERMAN.
